title: Normal levels of von Willebrand factor antigen in human body fluids.
abstract: von Willebrand Factor antigen is present in serum, plasma, synovial fluid and semen, and absent from other body fluids including breast milk, urine, saliva, and cerebro-spinal fluid. Levels are higher in plasma relative to serum. There is no difference between levels in different sexes, and no increase with age, but levels in cord blood are raised.
